Yes, Mexico has extradition. Mexico extradites individuals to foreign countries through two distinct legal pathways: bilateral extradition treaties with more than thirty nations, and the Ley de Extradicion Internacional (LEI) for countries with which Mexico has no treaty. The popular belief that Mexico is a “non-extradition country” is one of the most dangerous misconceptions in international criminal practice. Extradition from Mexico typically takes between six months and several years, and the outcome depends almost entirely on the quality of the legal defense mounted in Mexican federal courts.
This guide walks through the Mexican extradition process step-by-step, explains the difference between treaty-based and LEI extradition, lists the principal legal defenses, and answers the questions practitioners hear most often from clients facing a request from a foreign jurisdiction. It is written for non-lawyers but cites the actual statutory and constitutional provisions a Mexican federal judge will apply, including the LEI itself and the Mexican Constitution’s Articles 14, 16, 18, 103, and 107.
Does Mexico Have Extradition? Common Misconceptions
The most frequent search query reaching this firm is some variation of “is mexico a non extradition country,” “does mexico have extradition with us,” or “does mexico have an extradition treaty with the united states.” The short answer in every case is the same: Mexico is NOT a non-extradition country. Mexico is a fully active extradition partner with the United States, Canada, the United Kingdom, the European Union member states, most of Latin America, and many countries in Asia and Africa. The Mexican government extradites people to foreign countries every month.
Why does the “non-extradition” myth persist? Three reasons. First, the Mexican extradition process is slow compared to the European Union’s European Arrest Warrant or the streamlined US-Canada framework. A treaty case can run eighteen months even without complications, and an Amparo challenge can extend it by another two years. Second, Mexican courts genuinely refuse extradition in a meaningful percentage of cases — particularly where dual criminality, the political offense exception, or the death-penalty bar applies — and these refusals attract media attention. Third, in 2024 and 2025 the Sheinbaum administration publicly declined certain US extradition requests on sovereignty grounds, generating headlines that were misread by foreign audiences as a blanket policy of non-cooperation. None of these factors change the underlying reality: Mexico has more than thirty bilateral extradition treaties currently in force, and its domestic Ley de Extradicion Internacional permits extradition even where no treaty exists.
For a deeper analysis of why the “no treaty equals safety” myth is dangerous, see our analysis at The No-Extradition-Treaty Myth. The bottom line for anyone evaluating Mexico as a destination or shelter: assume Mexico will cooperate with a foreign extradition request. The legal defense is fought inside the Mexican system — not by relying on the absence of cooperation.
How Extradition From Mexico Actually Works (Procedure Step-by-Step)
Mexican extradition is a hybrid administrative-judicial procedure. Two branches of government participate: the executive branch, through the Secretaria de Relaciones Exteriores (SRE) and the Fiscalia General de la Republica (FGR), and the judicial branch, through a federal district judge. The procedure has nine principal stages.
Step 1 — Diplomatic Request to SRE
The requesting country files a formal extradition request through diplomatic channels addressed to the SRE. The request must include the underlying foreign arrest warrant or final sentence, a description of the alleged conduct, the applicable foreign criminal statute, and (under most treaties) prima facie evidence sufficient to justify a trial under the laws of the requested party. The SRE reviews the request for formal sufficiency and confirms that the foreign country has standing to request extradition under either a treaty or the principle of reciprocity.
Step 2 — SRE Forwards to FGR
If the request is formally sufficient, the SRE transmits it to the FGR. The FGR is the federal prosecutor and acts as the requesting party’s representative inside the Mexican legal system. From this point onward, FGR attorneys argue for extradition; the person sought (and counsel) argues against.
Step 3 — FGR Files Petition Before a Federal District Judge
The FGR files the formal extradition petition with a federal district judge in criminal matters (juez de distrito en materia penal). The judge has jurisdiction to decide the legal merits of the extradition request. Under Articles 19 and 20 of the LEI, the judge must hold a hearing and issue a written opinion (opinion juridica) that addresses every defense raised by the person sought.
Step 4 — Provisional Arrest
At any point after the FGR receives the request — and often before the formal petition is filed — the requesting country may seek the provisional arrest of the person sought. Provisional arrest is governed by Article 17 of the LEI and most bilateral treaties. The person can be detained for up to sixty days (extendable to ninety in some treaty regimes) while the formal documentation is being assembled. Provisional arrest is the moment most cases become public.
Step 5 — Federal Court Hearing
The federal judge schedules a hearing, typically with ten to thirty days’ notice. The hearing is the procedural heart of the case. The person sought, through Mexican counsel, presents legal defenses and supporting evidence. The FGR responds. The judge may order additional documentary evidence from the requesting country if the file is incomplete.
Step 6 — Defenses Presented
This is where defense strategy matters most. The person sought presents every applicable defense: dual criminality, political offense, statute of limitations, ne bis in idem, specialty rule, insufficient evidence, procedural defects in the foreign documentation, risk of torture, and so on. Each defense is litigated with citation to the LEI, the applicable bilateral treaty, the Mexican Constitution, and binding jurisprudence from the Suprema Corte de Justicia de la Nacion (SCJN).
Step 7 — Federal Judge Issues Opinion to SRE
After the hearing concludes, the federal judge issues a written legal opinion (opinion juridica). The opinion is addressed not to the parties directly but to the SRE, because the final extradition decision under the Mexican system is administrative, not judicial. The opinion advises the SRE on whether the legal requirements for extradition are met. In practice, an opinion that concludes the legal requirements are not met is almost always followed by the SRE.
Step 8 — SRE Final Administrative Decision
The SRE reviews the judicial opinion and issues a final administrative decision granting or denying extradition. Even where the judge has found the legal requirements met, the SRE retains discretion under Article 30 of the LEI to deny extradition on humanitarian, sovereignty, or public-policy grounds. This is the political-decision stage and is the moment when the Sheinbaum-era refusals reported in international media occurred.
Step 9 — Amparo Constitutional Challenge
The person sought may file an Amparo (juicio de amparo) constitutional challenge at multiple stages: against the provisional arrest order, against the federal judge’s opinion, and against the SRE’s final decision. The Amparo is reviewed by a federal collegiate circuit court and ultimately by the SCJN. A successful Amparo can vacate the extradition decision entirely. Amparo proceedings typically add six to twenty-four months to the overall timeline. See Amparo — Mexico’s Constitutional Injunction for a full treatment.
Treaty-Based vs LEI Extradition — Which Applies to You?
Mexico extradites under two parallel legal regimes. The first is treaty-based: Mexico has signed bilateral extradition treaties with more than thirty countries, and where a treaty applies, its terms govern. The second is the Ley de Extradicion Internacional (LEI), Mexico’s domestic statute that authorises extradition based on diplomatic reciprocity even where no treaty exists. Both regimes produce binding extradition orders. The lack of a treaty does not provide safety from extradition.
| Feature | Treaty-Based Extradition | LEI (Non-Treaty) Extradition |
|---|---|---|
| Legal basis | Bilateral treaty + LEI procedural rules | LEI alone + diplomatic reciprocity assurances |
| Required documents | As specified by the treaty | As specified by Articles 16-19 of LEI |
| Reciprocity assurances | Built into the treaty | Required as a separate diplomatic note |
| Specialty rule | Always included | Required as a diplomatic assurance |
| Death-penalty bar | Built into most modern treaties | Imposed under Article 10 of LEI |
| Political offense exception | Enumerated in the treaty | Imposed under Article 8 of LEI |
| Maximum provisional arrest | Per treaty (typically 60 days) | Per Article 17 LEI (60 days, extendable) |
| Mexican defenses available | Treaty + LEI + Constitution | LEI + Constitution |

Does Mexico Extradite To…
The single most-asked question is whether Mexico extradites to a particular country. The short answer is almost always yes — either via treaty or via the LEI. Below are concise answers for the ten countries that generate the most enquiries to this firm. Where a deeper guide exists, the link is provided.
United States
Yes. Mexico and the United States have extradited under the Treaty of 1978 for nearly half a century. The corridor is the most active extradition relationship in the Western Hemisphere. See our dedicated guide at Extradition Between Mexico and the USA.
Canada
Yes. Mexico and Canada have a bilateral treaty in force since 1990. Extradition between Mexico and Canada is routine and well-documented.
United Kingdom
Yes. Mexico and the UK extradite under a 1886 treaty (modernised by exchange of notes). The UK frequently uses the corridor for fraud and tax cases.
Spain
Yes. Mexico and Spain extradite under a treaty signed in 1978. Mexico-Spain is one of the busiest extradition corridors due to the shared language and active commercial relationships.
Germany
Yes. Mexico and Germany extradite under a treaty in force since 1978.
France
Yes. A bilateral treaty has been in force since 1994.
Italy
Yes. Mexico and Italy extradite under a treaty in force since 1899 (still applied with modern protocols).
Brazil
Yes. Mexico and Brazil have a bilateral treaty in force since 1938.
Russia
Possibly. Mexico and Russia have no bilateral treaty. Extradition would proceed under the LEI on the basis of diplomatic reciprocity. In practice, Russian requests are scrutinised heavily for political-offense issues and have a higher refusal rate than treaty requests.
China
Possibly. Mexico and China signed a bilateral extradition treaty in 2008 (in force from 2009). Chinese requests face elevated scrutiny on political-offense, death-penalty, and torture grounds.
Key Legal Defenses Against Extradition
Mexican extradition law provides a substantial catalogue of defenses. A skilled extradition lawyer in Mexico builds the case file around whichever defenses are factually available. The principal categories are below.
Dual Criminality
The alleged conduct must be a crime under both Mexican law and the law of the requesting country. If the foreign offense has no Mexican analogue — or if the conduct described does not satisfy the elements of any Mexican crime — extradition must be denied. Dual criminality is the most frequently litigated defense and is enshrined in Article 10, Section II of the LEI.
Political Offense Exception
Mexico cannot extradite for purely political offenses. The exception is enumerated in Article 8 of the LEI and in every modern bilateral treaty. The hardest line to draw is between purely political offenses (always exempt) and ordinary crimes with political connotations (sometimes extraditable). The defense argument requires careful framing of the underlying motivation and the historical-political context of the prosecution.
Death Penalty Bar
Mexico abolished the death penalty in 2005 and constitutionally prohibits extradition where the death penalty may be imposed. The requesting country must provide formal diplomatic assurances that the death penalty will not be sought or applied. Without those assurances, extradition is denied as of right.
Statute of Limitations
Extradition is denied if the underlying offense is time-barred under either the law of the requesting country or Mexican law. This defense requires careful calculation of the limitations period, including any tolling events, under both legal systems.
Ne Bis in Idem (Double Jeopardy)
If the person sought has already been tried, acquitted, or convicted of the same offense (in the requesting country, in Mexico, or in a third state), extradition is barred. This defense is codified at Article 7 of the LEI and is reinforced by Article 23 of the Mexican Constitution.
Specialty Rule
The requesting country may prosecute the extradited person only for the offenses listed in the extradition request. Extradition is denied where the requesting country’s past conduct (or specific representations) suggest it intends to prosecute for additional, non-listed conduct.
Insufficient Evidence
Most treaties (and Article 16 of the LEI) require the requesting country to provide evidence sufficient to justify a trial in the requested party’s courts. If the documentary file is thin, contradictory, or based on uncorroborated witness statements, the extradition can be defeated on evidentiary grounds alone.
Procedural Defects in the Foreign Request
The foreign documentation must be properly authenticated, translated into Spanish, and accompanied by all statutory and treaty-mandated annexes. A surprising number of cases fail because the requesting country submitted incomplete or improperly authenticated documents. A defense lawyer reviews every document for these technical defects at the outset of the case.
Risk of Torture or Inhumane Treatment
Mexico is a party to the UN Convention Against Torture and the Inter-American Convention to Prevent and Punish Torture. Extradition is denied if there are substantial grounds to believe the person sought would be subjected to torture or cruel, inhuman, or degrading treatment in the requesting country. This defense is particularly relevant where the requesting country has a documented record of mistreating prisoners or political opponents.
Constitutional Challenges via Amparo
Every defense above can also be raised as a constitutional violation through the Amparo procedure. Amparo gives a second forum — the federal collegiate circuit courts and the SCJN — to review the extradition decision. The Amparo can attack the provisional arrest, the federal judge’s opinion, the SRE’s final decision, or all three. See our deep-dive at Amparo — The Constitutional Injunction.
How Long Does Extradition Take in Mexico?
The honest answer is that extradition timelines vary widely. The basic procedural steps — from formal request to SRE final decision — typically take six to eighteen months. Provisional arrest accelerates the early phase; complex defenses and document gathering slow it down. Once the SRE issues its decision, the Amparo phase can add another six to twenty-four months. High-profile or politically sensitive cases can stretch to several years.
Recent examples illustrate the upper end of the curve. Several US extradition requests publicly declined or paused under the Sheinbaum administration in 2024-2025 had been pending in the Mexican system for two to four years before the political-level decision was made. The lesson for clients: extradition is rarely fast, and the time between provisional arrest and a final outcome is the window in which substantive defense work happens.
The Role of Amparo in Extradition Defense
The juicio de amparo is Mexico’s constitutional injunction. Codified in Articles 103 and 107 of the Mexican Constitution and developed through more than a century of SCJN jurisprudence, Amparo allows any person to challenge any government act — including an extradition decision — on constitutional grounds. There is no equivalent procedure in US, UK, or Canadian common law. Habeas corpus is the closest analogue but is far narrower in scope.
In extradition cases, Amparo serves three principal functions. First, it allows the defense to seek a suspension (suspension del acto reclamado) that pauses the extradition while the constitutional challenge is reviewed. Second, it provides an additional forum — the federal collegiate circuit courts — that has often been more willing than district judges to grant relief on novel constitutional theories. Third, it preserves the option of further review by the SCJN, which has decided several landmark extradition cases. For a complete treatment of Amparo strategy in extradition matters, see Amparo — Mexico’s Constitutional Injunction.
When You Need an Extradition Lawyer in Mexico
An extradition case in Mexico is not a matter for a general-practice lawyer. The procedure requires familiarity with federal court practice, the LEI, the relevant bilateral treaty, the Mexican Constitution, and SCJN jurisprudence. The right lawyer profile combines several attributes.
- Federal court experience. Extradition cases are heard exclusively by federal district judges in criminal matters. Lawyers without federal practice cannot effectively litigate them.
- Specialty in extradition and international cooperation. The treaties, the LEI, and the SCJN’s extradition jurisprudence are a discrete subspecialty. General criminal lawyers do not have this background.
- Bilingual practice. The foreign documentation must be reviewed in its original language. The client must be able to communicate without a translator.
- Encrypted communication. Confidentiality is critical. We use Proton encrypted email and never communicate sensitive case details over standard email or unencrypted messaging.
- Cross-jurisdictional evidence collection. Often the strongest defenses depend on documents and witnesses in the requesting country. The lawyer must be able to coordinate with foreign counsel to assemble the file.
- Amparo specialty. The Amparo phase is technically distinct from the underlying extradition procedure. A lawyer comfortable in both is essential.
If you or a family member is facing an extradition request — or has been provisionally arrested in Mexico — do not delay engaging counsel. The earliest stages are the most consequential.

Frequently Asked Questions
Does Mexico have an extradition treaty with the United States?
Yes. The US-Mexico Extradition Treaty has been in force since 1980 (signed 1978) and is the most active extradition corridor in the Western Hemisphere. Both countries extradite their own nationals to the other, subject to the treaty s defenses (dual criminality, political offense, death penalty assurances, etc.).
Can a Mexican citizen be extradited?
Yes. Article 14 of the Mexican Constitution and Article 32 of the LEI permit the extradition of Mexican nationals at the discretion of the executive. Mexico extradites Mexican nationals routinely under the US treaty and most other bilateral treaties. Citizenship is not a defense.
Can the US extradite from Mexico without a treaty?
In the case of the US-Mexico relationship the question is moot because the 1978 treaty governs. In general, however, Mexico can extradite to a non-treaty country under the Ley de Extradicion Internacional based on a diplomatic reciprocity assurance. The lack of a treaty does not provide safety.
What is the difference between extradition and deportation in Mexico?
Extradition is the formal surrender of a person to a foreign criminal jurisdiction under a treaty or the LEI, with full judicial process. Deportation (correctly called expulsion or deportacion under the Ley de Migracion) is an immigration removal and does not require judicial review of the underlying foreign charges. The Mexican government has, in some cases, used immigration deportation as an end-run around extradition; this practice is constitutionally challengeable through Amparo.
Does Mexico extradite for tax crimes?
Sometimes. Tax fraud is extraditable where the elements of the foreign offense satisfy dual criminality with a Mexican fiscal crime. Pure tax-collection matters (as opposed to fraud) can be more difficult for the requesting country, because Mexican law treats fiscal violations differently from common-law fraud.
How much does an extradition lawyer in Mexico cost?
Fees depend on case complexity. A typical full-service engagement covering district-court litigation and Amparo runs in the high five to low six figures (USD), with a substantial retainer. Provisional-arrest representation can be billed separately. We provide a written engagement letter with full fee disclosure before any work begins.
What if I am already in Mexico when extradition is requested?
You should engage Mexican counsel immediately, before any provisional arrest. Counsel can monitor for incoming requests, prepare a defense file in advance, and (where appropriate) file pre-emptive Amparo proceedings. Acting before arrest gives the defense substantially more strategic options.
Can I appeal an extradition order from Mexico?
Yes. The federal judge s opinion can be reviewed via Amparo, the SRE s final decision can be reviewed via Amparo, and the Amparo decision can in turn be reviewed by the federal collegiate circuit courts and ultimately the SCJN. The right of judicial review is robust and is one of the most important features of the Mexican system.
